MACHINE FOR MAKING INSOLES.

Specification of Letters Patent.

Patented July 20, 1915.

Application filed March 27, 1914. Serial No. 827,566.

To all whom it may concern Be it known that 1, WILLIAM FOWLER, a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Machines for Making Insoles, of which the fol lowing is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

The object of the invention is to provide a machine for turning up and pressing to gether the lips of a double lip insole. The insole is out before being fed to the machine, to form the two opposed lips and rubber cement is preferably applied to the lips before the sole is put into the machine. The purpose of the machine is to raise these lips to a perpendicular position on the insole, and to press them together, to form a strong and secure rib for sewing the insole to the shoe.

The object is accomplished and various other advantages, such as simplicity, great efficiency and ease of operation, are obtained by that certain construction and arrangement of parts to be hereinafter specifically pointed out and claimed.

In the drawings, Figure l is an insole with the double cuts formed therein. Fig. 2 is a cross section of the toe thereof. Fig. 3 is a similar view to Fig. 2, after the parts have passed through the machine. Fig. 4 is a longitudinal vertical section of the machine, with the driving parts in elevation. Fig. 5 is a detail perspective view of the lip turning means.

The insole l is prepared for the machine by making two cuts or channels 2 and 8 around the insole surface. The free ribbon of leather 5 so formed remains attached to the insole by the uncut portion 4. Rubber cement is then preferably applied to the rib hon-like strip 5, and the insole is ready to be fed into the lip turning machine. When the insole comes out of the machine, it will have the edges at each side of the ribbon bent up, pressed together and held by the rubber cement, which raised or bentup portions will remain in their erect position and form a flap for sewing the insole to the other parts of the shoe.

The machine which is the embodiment of this invention comprises a framework 6,

having suitable ournals for a driving shaft 7. A gear 12 on a shaft 13 (similarly mounted) meshes with a gear 14 on this shaft 7 An eccentric 15 on the shaft 13 has a rod 16, pivoted in the end 17 of a lever or walking beam 18. This walking beam is fulcrumed in the standards 19 and its forward end carries one of the lip turning tools. The standards 19 are slotted for lateral adjustment and secured by bolts 20 to lugs 21 on the framework.

Located at the forward end of the machine are two vertical shafts 22 and 28, which carry on their upper ends the knurled disks 24 and 25 respectively. The disk 24 is the revolving table upon which the insole is placed to be worked upon, and the disk 25 is the lip roll, which holds the insole on the revolving table, revolves in the opposite direction to the table and whose edge forms a vertical abutment against which the two lips are pressed together, by the tool mounted on the lever 18 to be hereinafter described.

The shaft 23 has a gear 26 which meshes with a worm on a shaft 11 mounted horizontally in the framework. A pulley 10 on this shaft is driven by a. belt 9, which also passes over a larger pulley 8 on the driving shaft 7. When the driving shaft is turned, the shaft 23 will then turn also imparting revolution to the lip roll disk 25. A gear 27 on the shaft 23 meshes with a gear 28 on the shaft 22 for the revolving table 24. This gear should be thick enough to change position with relation to the gear 27, because the shaft 22 is to be lowered by the saddle 122 connected to a foot treadle (not shown) so that the insole may be fed to or released from contact with the two disks 24 and 25. A socket 29 formed in the framework is provided to receive the spindle 31 by means of which the revolving table 24 is secured to the shaft 22, and a spring 30 is seated in the socket, around the shaft 22, to return the parts to operating position when downward pressure is released. This spring also gives resiliency to the support of an insole by the table, and the table thus adapts itself automatically to unevenness or different thickness of material to be operated on.

On the end of the lever 18 over the table 24 is secured a turret piece 32. Within this socket or turret piece is mounted the spindle 33 of a lip turning tool 34. A collar no 35 is mounted on the spindle and a spring 135 is placed within the turret piece to bear between this collar and a plug 36 in the end of the turret. The tool has a beveled and sharpened edge directed toward the periphery of the lip roll 25, and will be very rapidly reciprocated by the lever 18, as well as resilient in all positions because of the spring mounting. A plow or lip raising piece 37 is provided to work in connection with the lip roll. It has a beveled and sharpened edge 38 which raises the outer lip of the insole and is adjustably mounted alongside of the lip roll, by a slotted plate 39 and bolt 40.

Asthus described, the operation of my machine is as follows. The driving shaft is started, the table lowered and the heel of an insole placed on the table, under'the lip roll. The downward pressure is then released and the sole allowed to travel. The plow 37 will lift the outer lip of the insole, so that it stands vertically engaging the edge of the lip roll. The tool 84: is used to raise the inner lip and press it together with the outer lip against the lip roll. The operator has merely to guide the insole, as would be done in a channeling machine, and the insole comes out of the machine with a vertical. double lip, which is the desired result.

The fact that the vibrating lip turning tool is resiliently mounted on a walking beam gives a clawing movement to it. This diagonal or clawing motion sends the tool under the lip which is, of course, flat until raised and then presses it together with the other lip against the revolving disk 25. The action of the spring so modifies the motion of the walking beam as to adapt it perfectly to -my purpose. Since this motion of the vibrating turning tool and its product are novel, and as this motion is an important element of my invention, I do not desire to be limited to the precise means adopted, as the clawing motion might well be accom plished by some other means.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is v v 1. In a machine for turning up two lips previously cut in an insole, a revoluble worktable, a stationary lip-turning tool, a turret, a vibrating tool vertically-reciprocatingly carried by said turret, a plug seated in the upper end of said turret, a collar car ried by said vibrating tool, a spring inter: posed between said plugand said collar, and a revoluble roll having its edge extending over the work-table, said roll feeding the stock and cooperating with said vibrating tool in turning up the two lips and pressing them together.

2. In a machine for turning up two lips previously cut in an insole, a revolving work-table, a stationary lip-turning tool, a vibrating tool provided with a beveled lipturning surface, means for vertically-yieldingly supporting said vibrating tool, and a revoluble roll having its edge extending over the work-table, said roll feeding the stock and cooperating with said vibrating tool in turning up the two lips and pressing them together.

3. In a machine for turning up and pressing together two lips previously out in an insole, a revoluble work-table, a revoluble roll having an edge extending over the worktable, means located adjacent to, said edge to turn up one lip before it reaches said edge, means located opposite said edge for turning up the other lip and means for imparting vibratory motion to said last named means in substantially a diagonal direction.

4. In a machine for turning up and pressing together two lips previously cut in an insole, a revoluble work-table, a revoluble roll having an edge extending over the worktable, means located acent to said edge to turn up one lip before it reaches said edge, means located opposite said edge for turning up the other lip, means for imparting vibratory motion to said last means in substantially a diagonal direction and a spring operating together with said vibratory means to impart a clawing motion to said means.

5. In a machine for turning up and pressing together two lips previously cut in an insole, a revoluble work-table, means for resiliently supporting the table, an oppositely revoluble disk above the table, a means for turning up one lip of the insole located adjacent to the edge of the disk, a vibrating tool to turn up the other lip, located opposite the edge of the disk, and means for resiliently mounting the vibrating tool.

6. In a machine for turning up and pressing'together two lips previously cut in an insole, a revoluble worlvtable, means for resiliently supporting the table, an oppositely revoluble disk above the table, a means for turning up one lip of the insole located adjacent to the edge of'the disk, a vibrating walking beam, a tool for turning up the other lip, located opposite the edge of'the disk and means for resiliently mounting the tool on one end of the walking beam.
